• When "Communication Mode" is set to "Multicast", if a local station and a CC-Link IE TSN Class A remote station are both
connected on the end side via a switching hub, communication may not be possible depending on the type of the device.
The communication will be enabled by configuring settings with the switching hub so that multicast frame (with multicast
MAC addresses 09:00:70:00:10:02 and 09:00:70:00:10:05) will not be transferred to the port of the CC-Link IE TSN Class
A remote station.
